The website is no longer active now, however, there are many such scams today and most such companies don't have a website as well and may advertise through well known classified websites.
Key pointers are:
1. Only gmail address to make contact. They don't want to be tracked down for running a scam and so they will have only a gmail address which could change regularly. The person running the scam could be based in any country and may claim to be present in another country.
2. Mobile numbers to make contact which suddenly changes. Many scamsters, will only provide a mobile number and that too on which incoming may be blocked or may get blocked after your initial contact.
3. Job offer without interview or without and English language testing. Let's be honest, if you were running a company, would you hire someone without knowing or interviewing that person? Exactly! why would someone hire you without an interview or any kind of screening simply based on some money you have paid? NO company anywhere in the world offers a job without a formal interview face to face (at least through Skype)!
4. Multiple company names. Please do at least some basic internet search about the company/ individual that you may be dealing with and you may find on forums or websites that the company has changed multiple hands or has changed names a few times. People may be talking about the same company name or a similar name which has changed a few times. All these are signs that you should be careful of that company.
Although the Australian Department of Immigration issues visas electronically over email, they are not e-visas and each visa category has a corresponding 3 digit visa subclass number (for e.g.: for short term employment up to 4 years the visa subclass will be 457). Most people offering jobs such as the ones mentioned above will not give you visa details as they themselves are not aware or they don't want you to look up the details.
For all kind of work visas for Australia, your occupation has to be in demand in Australia and this information is available on the DIBP website:
Not only does your occupation have to be in demand, your employer in Australia has to justify to the government as to why they should hire you against someone who is a local, Australian permanent resident or Citizen.
The only legitimate way to find a job in Australia is through an authorised placement consultant who specialises not only in recruitment for the country you are looking for but also in the field that you specialise in.
